Phonetics, Phonology, and Morphology

A widely-cited study investigating effects of recognition difficulty on the phonetic realization of words (Wright, 2004). Factors of lexical competition in vowel articulation. In J. Local, R. Ogden & R. Temple (Eds.), Papers in laboratory phonology, Vol. VI (pp. 26–50)) reported that vowel dispersion, i.e. distance from the center of the talker's F1/F2 space, was greater in words that represented difficult recognition targets (‘...

This paper provides evidence that multiple acoustic cues involving the presence of low-frequency energy integrate in the perception of Korean coronal fricatives. This finding helps explain a surprising asymmetry between the production and perception of these fricatives found in previous studies: lower F0 onset in the following vowel leads to a response bias for plain [s] over fortis [s*], despite the fact that there is no evidence for a corresponding acoustic asymmetry in the production of [s] and [s*]. A fixed classification task using the Garner paradigm provides evidence that low...

A complete neurobiological understanding of speech motor control requires determination of the relationship between simultaneously recorded neural activity and the kinematics of the lips, jaw, tongue, and larynx. Many speech articulators are internal to the vocal tract, and therefore simultaneously tracking the kinematics of all articulators is nontrivial — especially in the context of human electrophysiology recordings. Here, we describe a noninvasive, multi-modal imaging system to monitor vocal tract kinematics, demonstrate this system in six speakers during production of nine American...
